IMPROVEMENT IN STEAM-HEATERS.
Specification forming part of Letters Patent No. 117,111, dated July 1S, 1871.
heating apparatus, whereby a greater amount of heating-surface is obtained, as well as greater strength and better circulation. It consists in a peculiar arrangement of pipes in a steam-heating apparatus, and also in dividing the lower section in two parts, all of which will be more fully described in the specilication, enabling oth` ers skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a vertical cross-section of the apparatus or boiler. Fig. 2 is a top view of one of the sections. Fig. 3 is a top view of the lower or grate-section. Fig. 4 is a cross-section of the same.
In the figures like letters refer to like parts.
In the drawing, A represents the outer shell of a steam-heating apparatus or boiler, made in sections, bolted together by bolts a a. The lower section B rests upon the brick ash-pit B', and is provided with the grate c c, and is divided by a hollow partition, B, being inclined as shown in Fig. 4. Through this partition is cast a number of air-passages, b b, through which the air passes, thereby cooling the partition and assist ing in the combustion of the fuel. The object of this partition is that two separate fires may be made, and, if preferred, only one side may be used, thereby saving one-half the amount of fuel. In this section is also arranged the furnace-door B of the ordinary construction. The sections C and D are provided with four or more pipes, d d', inclining and joining in the center, and bolted together through the center by a bolt, d, leaving a space all around it for the water to circulate. In the drawing two of these sections are shown, but for a larger boiler more sections may be used, and the pipes d d in each may be set around, as shown by the dotted lines in Fig. 2, so as to obtain a greater calorimeter or heating-surface. In the top section E, forming the dome or steam-drum, I arrange four (more or less) flucs or pipes, running at right angles to each other, and, by makin g them in this manner, I obviate the necessity of an elbow, as heretofore used. The sections are all connected between their inner and outer shells, forming the water-space j' by the usual openings g g.
The great advantages of my apparatus over all others heretofore made are: a better circulation of the water is obtained; a greater amount of heating-surface, as the water being in the hollow partition, and thereby in direct contact with the lire, it is sooner heated. If desirable, by lighting only one of the tires one-half the fuel is saved. The outlet or escape-fines having no elbow, the smoke is sooner got rid of, if desired, and the casting is easier and cheaper to make. By bolting the pi pes togetherin the center greater strength is given to the boiler, and, by their inclined shape, they are not so liable to be cracked or broken by the contraction or expansion ofthe same, or to hold the sediment or scale contained in the water.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-
l. The hollow partition B, provided with airpassages b b, in combination with the grates c c, substantially as shown and for the purpose set forth.
2. The arrangement of the pipes d d', connected in the center in the sections C D and bolted together, in the manner and for the purpose set forth.
3. The arrangement, in the heating apparatus herein shown, of the shell A, having sections B C D E, the partition B, grates e, pipes d d, bolts d, and iiues E', when all constructed and arranged as shown, and for the purpose set forth.
